Function:
Alternate
Address:
Port D is an 7-bit special-function port that shares four of its pins with the
serial peripheral interface (SPI) module and three of its pins with two
timer interface (TIM1 and TIM2) modules. Port D also has software
configurable pullup devices if configured as an input port.
The port D data register (PTD) contains a data latch for each of the
seven port D pins.

Freescale Semiconductor, Inc.
These read/write bits are software-programmable. Data direction of
each port D pin is under the control of the corresponding bit in data
direction register D. Reset has no effect on port D data.
The PTD6/T2CH0 pin is the TIM2 input capture/output compare pin.
The edge/level select bits, ELSxB:ELSxA, determine whether the
PTD6/T2CH0 pin is a timer channel I/O pin or a general-purpose I/O
pin. See
